When should I use a windscreen, and what is the material used?

The recommended material for windscreens is open cell foam. This allows the sound to pass through while reducing the impact of air flow on the microphone. Turbulence generated by wind passing by a microphone may be detected as noise. Windscreens are recommended with wind speeds up to 20 meters per second and help keep dirt and moisture off the microphone. This helps to keep the sensitivity stable and reduces contamination, extending the life of the microphone. Windscreens can attenuate signals at higher frequencies.
